Abstract
PURPOSE: To prevent forgery, abuse, etc., of a card by using a magnetic card where a magnetic medium is applied onto a magnetic film and by providing a head for magnetic saturation of the magnetic medium above besides a recording and reproducing head to form a magnetic card recording and reproducing device.
CONSTITUTION: A magnetic card is used where a low-coercive force magnetic medium 3 is applied and formed on magnetic film 2 of a high coercive force on plastic sheet 1. Meanwhile, a recording and reproducing head consisting of recording head core 4 having coil 6 and reproducing head core 5 having coil 7 and a head for magnetic saturation which consists of permanent magnet 9 and head cores 8 for magnetic saturation and has a magnetizing force to saturate magnetically magnetic medium 3 and have no influence upon the high-coercive force magnetic film are arranged on the magnetic card above so that the gap of cores 8 may include the gap of cores 4 and 5, thus obtaining a recoding and reproducing device.
